The second message states that the linearization of this block causes the model to

linearize to zero. As shown in the Linearization section, the block is linearized to zero.

Therefore, modifying the block linearization is a good first step toward obtaining a

nonzero model linearization.

Relinearize Model

After setting the Saturation block to be treated as a gain, relinearize the model. For now,

ignore the diagnostics for the two Trigonometric Function blocks.

To relinearize the model, on the Linear Analysis tab, click Bode Plot 1. The Bode Plot
